Question

What is the benefit of using "at length found myself" rather than a more direct syntax?

Answer 1

During the whole of a dull, dark, and soundless day in the autumn of the year, when the clouds hung oppressively low in the heavens, I had been passing alone, on horseback, through a singularly dreary tract of country, and at length found myself, as the shades of the evening drew on, within view of the melancholy House of Usher.—Poe, "The Fall of the House of Usher"
